CBX8 promotes the metastasis of HCC cells. a CBX8 protein expression in L02 cell line and HCC cell lines as indicated was detected by Western blot (right panel, gray scan results normalized to β-actin). b CBX8 mRNA expression in SK-Hep-1 cells introduced with four specific shRNAs targeted CBX8 and a control shGFP by semi-quantitative RT-PCR (right panel, gray scan results normalized to GAPDH). c Invasion and migration ability of CBX8 knock-down cells was analyzed by wound healing. **P < 0.01 is based on the Student t test compared to shGFP cells. d Invasion and migration ability of CBX8 knock-down cells was analyzed by Transwell assay. **P < 0.01 is based on the Student t test compared to shGFP cells. All results are from three independent experiments
